MCP1811A/11B/12A/12B

Ultra-Low Quiescent Current LDO Regulator

for Long-Life Battery-Powered Applications

Features

Description

• Ultra-Low Quiescent Current: 250 nA (typical)

• Ultra-Low Shutdown Supply Current:

- 10 nA typical for MCP1811A/12A

- 5 nA typical for MCP1811B/12B

• Output Current Capability:

The MCP1811X/12X devices are 150 mA (MCP1811X)

and 300 mA (MCP1812X) Low-Dropout (LDO) linear

regulators that provide high-current and low-output

voltages while maintaining an ultra-low 250 nA of

quiescent current during device operation. In addition,

the MCP1811B/12B can be shut down for 5 nA (typical)

supply current draw.

- 150 mA for MCP1811X (Note 1)

- 300 mA for MCP1812X

The MCP1811X/12X family comes in nine standard

fixed output voltage versions: 1V, 1.2V, 1.8V, 2.0V,

2.5V, 2.8V, 3.0V, 3.3V and 4.0V.

• Input Voltage Range: 1.8V to 5.5V

• Standard Output Voltages (V_R): 1V, 1.2V, 1.8V, 2.0V,

2.5V, 2.8V, 3.0V, 3.3V and 4.0V; for any other voltage

options (between 1V to 4V), please contact your local

sales office

The 150/300 mA output current capability, combined

with the low output voltage capability, make the

MCP1811X/12X device family a good choice for new

ultra-long life LDO applications that have high-current

demands, but require ultra-low power consumption

during Sleep periods.

• Stable with Ceramic Output Capacitor:

1.0 μF (MCP1811X) and 2.2 μF (MCP1812X)

• Overcurrent Protection

• Output Discharge (Shutdown mode,

SHDN = GND) MCP1811A/12A

The MCP1811X/12X devices are stable with ceramic

output capacitors that inherently provide lower output

noise, and reduce the size and cost of the entire

regulator solution. Only 1 μF (2.2 μF for MCP1812X) of

output capacitance is needed to assure the stability of

the system with a low noise output.

• Available for the Following Packages:

- 3-Lead SOT-23

- 3-Lead SC70

- 4-Lead 1 x 1 mm UDFN

- 5-Lead SOT-23

The MCP1811X/12X family can be paired with other

ultra-low current devices, such as Microchip’s eXtreme

Low-Power (XLP) technology devices, for a complete

ultra-low power solution.

- 5-Lead SC70

Applications

Note 1: The MCP1811X and MCP1812X desig-

nations refer to MCP1811A/11B and

MCP1812A/12B, respectively.

• Energy Harvesting

• Long-Life, Battery-Powered Applications

• Smart Cards

• Ultra-Low Consumption “Green” Products

• Wearable Electronics (smart watches, bracelets,

headsets)

• Medical Devices (hearing aids)
